4 months ago These are two different types of keys.
The first is PKCS#8 and can be parsed with the pkcs8 crate. Note it begins with BEGIN PRIVATE KEY.
The second one is PKCS#1 and can be parsed with the pkcs1 crate. Note it begins with BEGIN RSA PRIVATE KEY.
Hello! I wrote small code to decode private key from pem data.
const SAMPLE: str = "-----BEGIN PRIVATE KEY----- MIGHAgEAMBMGByqGSM49AgEGCCqGSM49AwEHBG0wawIBAQQgaWJBcVYaYzQN4OfY afKgVJJVjhoEhotqn4VKhmeIGI2hRANCAAQcrP+1Xy8s79idies3SyaBFSRSgC3u oJkWBoE32DnPf8SBpESSME1+9mrBF77+g6jQjxVfK1L59hjdRHApBI4P -----END PRIVATE KEY----- "; let priv_key = parse(SAMPLE).unwrap(); let private_key: PrivateKeyInfo = PrivateKeyInfo::try_from(priv_key.contents()).unwrap(); println!("Algorithm: {:?}", private_key.algorithm.oid); println!("Private key: {:?}", private_key.private_key); println!("Public key: {:?}", private_key.public_key);This code could run correctly. If I change SAMPLE TO:
